Does Akinola support jailing gays?

Yes, according to Raising Kaine:

Jailing gays? Jailing gays?! Later, the article elaborates that Akinola "supported a new Nigerian law that penalizes gay activity, whether private or 'a public show of same sex amorous relationship,' with jail time."

No, according to Bishop Minns, priest-in-charge at Truro:

A Statement of Clarification

In a recent Washington Post article, Archbishop Peter J. Akinola was characterized as “an advocate of jailing gays.” That is not true.

Archbishop Akinola believes that all people—whatever their manner of life or sexual orientation—are made in the image of God and deserve to be treated with respect. “We are all broken and need the transforming love of God,” Archbishop Akinola said to me during a recent conversation.

Archbishop Akinola also said, “Jesus Christ is our example for this. He refused to condemn the woman caught in adultery instead he said. ‘Go now and sin no more.’ That is an essential part of the message of the Gospel and the teaching of our congregations.”

Perhaps the Archbishop disagrees with part of the Nigerian law.

Or perhaps he uses reason to interpret scripture:

Rom 1:26 For this reason God gave them up to dishonorable passions. Their women exchanged natural relations for unnatural,
Rom 1:27 and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in their own persons the due penalty for their error.
Rom 1:28 And since they did not see fit to acknowledge God, God gave them up to a base mind and to improper conduct.
Rom 1:29 They were filled with all manner of wickedness, evil, covetousness, malice. Full of envy, murder, strife, deceit, malignity, they are gossips,
Rom 1:30 slanderers, haters of God, insolent, haughty, boastful, inventors of evil, disobedient to parents,
Rom 1:31 foolish, faithless, heartless, ruthless.
Rom 1:32 Though they know God's decree that those who do such things deserve to die, they not only do them but approve those who practice them.
Rom 2:1 Therefore you have no excuse, O man, whoever you are, when you judge another; for in passing judgment upon him you condemn yourself, because you, the judge, are doing the very same things.
Rom 2:2 We know that the judgment of God rightly falls upon those who do such things.
Rom 2:3 Do you suppose, O man, that when you judge those who do such things and yet do them yourself, you will escape the judgment of God?
